Some of the special prime lenses are the MACROs and Fisheyes.

MACROs allow for a very close-up shot, with a very wide aperture (usually f/2.8), allowing for exceptional clarity, detail and extremely shallow depth of field, effectively "fuzzing out" the areas in front of and behind the subject.

Below is a listing of the "currently" available lenses:

MACRO PRIMES
SONY DT 30mm f/2.8 Macro (ø55mm)
SIGMA 50mm f/2.8 EX DG (ø55mm)
SONY 50mm f/2.8 (ø55mm)
SIGMA 70mm f/2.8 EX DG (ø62mm)
TAMRON SP AF 90mm f/2.8 Di 1:1 MACRO (ø55mm)
SONY 100mm f/2.8 Macro (ø55mm)
SIGMA 105mm f/2.8 EX DG (ø58mm)
SIGMA 150mm f/2.8 EX DG (ø72mm)
SIGMA 180mm f/3.5 EX DG (ø72mm)
TAMRON SP AF 180mm f/3.5 Di LD 1:1 MACRO (ø72mm)


Fisheye lenses offer a distorted aspect to your image, forgoing the rectilinear correction of the standard optic. Normally, because of the rather eccentric shape of the first element, these type of lenses cannot accommodate filters and therefore have no filter ring on the front of the lens. Many do have a gelatin-filter ring in the rear of the lens to add various "style" elements to the image.

Fisheye PRIMES
SIGMA 4.5mm f/2.8 EX DC Circular Fisheye HSM
SIGMA 8mm f/3.5 EX DG Circular Fisheye
SIGMA 10mm f/2.8 EX DC Fisheye HSM
SIGMA 15mm f/2.8 EX DG Diagonal Fisheye
SONY 16mm f/2.8 Fisheye
